It seems a reasonable assumption that there are, at any given moment, millions of users running Venmo, one of the most popular online payments solutions out there. Right now the service is seeing all-time highs of usage, especially after their new iPhone app update was met with great praise.

The reason for this surprising success is a relatively new phenomenon that has taken social media by storm. It’s the phrase “I’m a paid user,” a word rarely uttered outside of those who have found success with the money transfer service. What’s causing such an outpouring of interest in this shorthand catchphrase? The key is how the brand operates.

There are two distinctly different ways of looking at it. At the core level, some think the secret to this rapid growth lies in the fact that Venmo is such a simple idea. The receiver, in this case the person sending the payments, doesn’t have to know anything about the sender’s identity. That’s why they put it out to bid.

Plus, there’s that extra layer of security that Venmo offers up. Payments that pass the Venmo verification check are directly cleared for the provider. Paying the fee for this is no different than paying it on any other payment platform. To give an idea, Venmo customers are most often asked to pay a 2% fee when they send and receive money. This makes the sender a known entity, guaranteeing that the payment will be given the nod even if the recipient doesn’t have the numbers. It’s essentially the same thing as a credit card company in that way.

For others, it’s a bigger question. Some see it as a recognition of the modern, ephemeral lifestyle. Whatever it is, the discussion around the phrase “I’m a paid user” has been practically everywhere for the past week. As a result, you’re seeing a lot of users reaching out to us asking what they should do with all these invoices and the offer to send more payments for them. Which one is the correct approach? And should people only agree to payments they can comfortably cover?

There’s also an etiquette aspect that’s in the news. What about women who want to use their own personal funds to send money to their male friends? At the core level, it’s up to you to decide what feels comfortable. Of course, if you’re very far away from the person who sends you the payment, it may not be such a problem. But if you’re closer to the recipient, is it really appropriate to wire them money?

The problem is that it may all be a bit too straightforward. The idea that the Venmo user is just a person who has found himself on a winner streak. So this gets trickier, especially if you’re not quite that familiar with each other. So is it better to set your price point? Is it important to seal the deal in person? Or is it important to have a chat about payment plans so that you can handle future payments on the go? It’s worth putting those questions to the Venmo community.

Now we’re just waiting for their contribution about how they got their “I’m a paid user” name.
